Prognostic factors after acute mesenteric ischemia: which patients require specific management?

Area of Science:

• Vascular Surgery
• Gastroenterology
• Critical Care Medicine

Background:

• Acute mesenteric ischemia (AMI) presents diagnostic and therapeutic challenges.
• Limited data exists on AMI outcomes, with only one center reporting survival rates.

Purpose of the Study:

• To analyze mortality and identify predictive factors for acute mesenteric ischemia (AMI).
• To inform the development of a dedicated intestinal stroke center.

Main Methods:

• Retrospective analysis of 173 patients with AMI from January 2015 to December 2020.
• Patients were categorized into early mortality (within 30 days) and alive groups.
• Comparison of clinical, laboratory, and radiological characteristics between groups.

Main Results:

• Overall mortality rate was 61%, with 78% of deaths occurring within 30 days.
• Protective factors included history of abdominal surgery, anticoagulation, and antiplatelet therapy.
• Predictive factors for mortality were age >70 years and history of coronary disease.

Conclusions:

• AMI is a severe condition with high morbidity and mortality.
• Improving diagnosis and management, especially for older patients with coronary history, is vital.
• Establishing a dedicated organizational structure for AMI care is recommended.
